Third-party browser libraries for ALFAJAR POS
==============================================

alfajar-qr-1.0.js   (included)
  QR code encoder used by receipts and A4 invoices.
  Source: QRCode for JavaScript by Kazuhiko Arase, Copyright (c) 2009, MIT licence
  (http://www.opensource.org/licenses/mit-license.php). Copies of the sources are in tools/qr-source/.
  Built by:  node tools/build-qr-library.js   (Node.js 18 or later; no network needed)
  Exposes:   qrcode(typeNumber, "M") -> addData(text), make(), createSvgTag(cellSize, margin)
  Test:      encoded samples decode back to the same text (see the release evidence, qr-library folder).

Without this file, receipts show a "library missing" notice and still print the TLV text.
The page health check (Settings > Health) reports the file as present or missing.
